Comparative genomic relationships between L. perenne, B. distachyon , S. bicolor and rice relative to DArT marker distribution. Scatter plot illustrating the conserved syntenic relationships between the relative position of gene-based markers on the L. perenne linkage groups (Lp1 study), the physical position of their most probable sequence alignments on the B. distachyon, S. bicolor and rice pseudomolecules and the genetic distance spanned by the DArT markers mapped to each L. perenne linkage group. The position of the S. bicolor markers from pseudomolecule 1 which align with genetic markers which map to L. perenne linkage group 4 are offset slightly to avoid direct overlap with the B. distachyon alignments to the same linkage group.
